ShowMiiWads alternative/Mono release?

I'm trying to inject certain WADs into my NAND backup in order to load with USB Loader GX.

I've already tried going through the entire method of injecting the WAD through USB Loader GX itself after I put it on either my SD card or my USB device. When I tried to load the installed WAD, though, all I got was a black screen. After looking up that issue, multiple sources claimed that the problem occurred because of the built-in apps of USB Loader GX and that I should use ShowMiiWads.

The problem is, I'm using Ubuntu 12.10 rather than Windows, and SMW doesn't even work on Wine (Windows compatibility layer for Linux) with Mono (.NET Framework alternative that can also be used to run certain .NET programs with Wine) installed. So I'm looking for one of these alternatives:
1. A Windows version of ShowMiiWads compiled to work with Mono/Wine
2. A Windows alternative for ShowMiiWads compiled to work with Mono
3. Any other sort of alternative for SMW, be it for Linux or for Windows

Well, Crossover is essentially a Pay-to-use variation of Wine, so I didn't get to it yet as ShowMiiWads is the only Windows app that I needed and couldn't run with Wine so far (out of just a handful, because I usually manage to find a native Linux alternative for all my needs). Usually I get everything to work after messing around with Winetricks.

If Crossover is confirmed to support SMW while the standard version of Wine doesn't, I'll gladly get it, but I'd like to know if any other Linux user around here faced the same problem and found a different solution (or at least get some sort of confirmation regarding SMW being supported on Crossover if possible).
